Abstract: In this study, the technical feasibility of the mineral carbonation of flue gas desulfurization (FGD) gypsum to sequester CO2 was assessed by considering various reaction parameters. Unlike other natural and industrial materials, FGD gypsum showed very high carbonation reactivity at room temperature and atmospheric pressure. Under optimum conditions, calcium carbonate with a purity exceeding 90% could be obtained within 10 min at a carbonation rate of approximately 95%. Thus, mineral carbonation of FGD gypsum was found to be technically feasible.
